Android string encoding and html entities converting

You can add denpendency:

implementation group: 'org.apache.commons', name: 'commons-text', version: '1.3'

And use StringEscapeUtils.unescapeHtml4(s), then get the result.

to decode Html String you can use Html.fromHtml()

like

Html.fromHtml((String) htmlCode).toString();

if you want reverse

than you can use TextUtils.htmlEncode()
